Currency exchange instability

Hello everyone, how are you?

I would like to start by praising the plugin. CURCY is really an excellent plugin, with extensive configurations and it works very well in general! However, I am having specific problems with complaints about incorrect currency, with customers from Australia seeing US dollars and those from outside Australia seeing Australian dollars. Understand that this is unusual and is usually resolved by clearing the WordPress cache, but even though this rarely happens, it hurts our sales.

Do you have cases like this? Because while one visitor sees it correctly, another does not. I have a recording of Clarity here, for example, that shows the Dollar.
